How does the kidney filter blood?

How does the kidney filter blood?Many people do not realize how vital their kidneys are to their overall health until an issue arises and they need to seek medical care. Knowing what your kidneys do and how they function can go a long way toward maintaining good health before a problem occurs or understanding the treatment process once you are under a urologist’s supervision.

What Do My Kidneys Do?

Your kidneys are basically your body’s filtration system. Every minute, approximately half a cup of blood flows through them. As the blood flows through, waste products are removed, as is excess water; the levels of minerals and salt are also adjusted if need be. Although around 150 quarts of blood are filtered by your kidneys every day as it continually cycles through your body, only about 1-2 quarts of urine are produced from the waste products and excess water. The urine then flows to the bladder through a tube called the ureter.

How Do My Kidneys Work?

Inside each kidney, there are about a million tiny filtration units called nephrons. The nephrons are made up of a filter called a glomerulus and a tube called a tubule. Blood flows through the glomerulus, where waste and excess water or minerals are filtered out. The tubule then sends the filtered substances to collect in the kidneys before flowing through the ureter to the bladder, while the newly-filtered blood is returned to the rest of the body. There are so many nephrons in your kidneys that even if more than half of them are no longer working, you may not notice any issues or symptoms.

What Happens If Something Goes Wrong?

Many things can occur to interrupt the function of your kidneys. Warning signs of kidney disease include an increased need to urinate, especially at night, blood in the urine, foamy urine, cramping muscles and swollen ankles and feet. These are all signs that something could be wrong with the filtration system in your kidneys, causing issues with fluid and electrolyte levels in your body.

Another common problem is kidney stones. When there is a buildup of certain waste products in the kidneys and not enough fluid to flush them out, these waste products can crystallize and form stones that cause extreme pain as they leave the body. If you suspect you are dealing with kidney stones, kidney disease, or other problems with your urinary system, it’s important to talk to a doctor right away, like the urologists at St Pete Urology, who will be able to diagnose any issues and help you and your kidneys return to normal healthy function as soon as possible.

Infertility Treatment Options for Men & Women

Infertility Treatment Options for Men & WomenFor couples struggling to conceive a child, life might feel like a carousel, trying for the brass ring, month after month. It can put a lot of pressure on the relationship. But now there are fertility treatments that can put the chances of conception in your favor.

What are the different types of fertility treatments?

Today we have more technology for diagnosing and treating infertility than ever before. Fertility assessments should be done on both partners to determine which treatments can help, and whether it is a male or female infertility issue.

Female Options for Fertility Treatment

Fertility treatments can include medications to regulate hormones and ovulation, which are often combined with minor surgery approaches. Assisted Reproductive Technology, or ART for short, encompasses several procedures to help you conceive. Some ART procedures make it easier for the sperm to fertilize an egg, and others help with getting the egg to implant in the lining of your uterus.

Common ART fertility treatments are:

Intrauterine Insemination (IUI), in which healthy sperm is collected and then inserted directly into the uterus when you are ovulating.

In Vitro Fertilization (IVF), in which eggs are taken from the ovaries to be fertilized by sperm in the lab where they can develop into embryos. Then a doctor implants the embryos into your uterus after they grows for 3 to 5 days.

GIFT, short for Gamete IntraFallopian Transfer, and ZIFT, Zygote IntraFallopian Transfer. In GIFT, the egg and sperm are collected and immediately placed in a fallopian tube. With ZIFT, the egg(s) and sperm are combined in a lab, resulting in a fertilized egg, which then is placed into the tube at 24 hours.

Cryopreservation, which is known as “freezing” your eggs, sperm or embryos, along with donated eggs or embryos, as well as surrogate mothers who carry the embryo to term.

Both fertility drugs and hormones can be used to help determine when the woman is ovulating or ensure proper levels of hormones. Surgery can remove tissue, such as in cases of endometriosis, or be used to open blocked fallopian tubes.

Enlisting donor sperm, eggs or surrogate mothers, is popular with single people and same-sex couples who desire a baby. Donor sperm or eggs can be the solution if either partner has fertility issues.

Male Options for Fertility Treatment

There are various treatment options if the male needs help with sperm counts, quality or motility. Surgery by a qualified urologist is recommended if the cause is a varicocele (widened veins in the scrotum) or for any blockage in the vas deferens, the tubes that carry the sperm. Antibiotics can be used to treat infections in the reproductive organs, and medications can treat problems with ejaculation or erections. Another option is hormone treatment.

If you wish to conceive but are having problems, our team of specialists at St Pete Urology is experienced in working with couples to make assessments and help in achieving your dreams. For more information, visit the St Pete Urology website.

Can Male Infertility Be Treated?

Can Male Infertility be treated?For many couples, trying and not being able to conceive a child is a stressful, emotional and frustrating time. Up to 15% of couples are infertile, meaning that they cannot conceive a child despite actively trying for a year or more. And for that 15%, over a third of these problems stem from issues caused by male infertility.Male infertility is the inability to conceive a child. There are no obvious signs that a man is infertile, and he may not realize it until he and his partner are unsuccessful in their attempts. However, in some cases like hormonal imbalances, inherited disorders and testicular vein issues, symptoms may exist. These can include erectile dysfunction, difficulty ejaculating, ejaculating in small volumes, decreased sexual desire, or abnormal breast growth.

There are numerous causes that can lead to male infertility. A common and easily reversible symptom is Varicocele, the swelling of the veins that release fluid from the testicles. Infections also can be the cause of male infertility, as they can cause issues with sperm health and production. In some cases, treating the infection can treat the issue, but not in all instances. Another cause of infertility is retrograde ejaculation, an issue where semen enters the bladder during orgasm. Infertility can also be a symptom of certain tumors.

In addition to medical causes for infertility, there are also environmental and lifestyle factors that can be attributed. Extended exposure to industrial chemicals or heavy metals can contribute to low sperm counts. Radiation or x-ray exposure can cause temporary reductions in sperm count. As for lifestyle causes, drug, alcohol, tobacco use and emotional stress can be contributing factors to male infertility.

Although a specific cause of male infertility may not always be clear, there are plenty of treatments available, and a urologist may be able to assist you. Surgery can help to open pathways in constricted veins to allow more semen to flow freely. Antibiotic treatments will clear up any infections that may be causing infertility. Hormone treatments and medications are useful in some cases. And in other cases, assisted reproductive technologies, like the surgical extraction of sperm for fertilization, may be recommended by your urologist.

For many couples the inability to have a child can cause a lot of stress and anxiety. But there is hope. Urologists and fertility doctors have dedicated their lives to helping couples who want to have children. Doctors, like those at St Pete Urology, can help you learn more about your condition and help you start your family. For more information, visit the St Pete Urology website.

What Causes Bladder Incontinence

Urinary incontinence is basically the loss of bladder control or leaking urine. Women experience urinary incontinence twice as frequently as men. One reason for this difference is that childbirth and pregnancy, as well as menopause, can contribute to making urinary incontinence more likely. There are two common types that affect women, stress incontinence or urge incontinence (or overactive bladder, also known as OAB).

Urine is made by the kidneys and is stored in the bladder. There are muscles in the bladder that tighten, causing a need to urinate. When these muscles tighten, urine is forced out of the bladder through the urethra. Urination happens when the sphincter muscles surrounding the urethra relax, letting urine out of your body. Urinary incontinence can make you leak small amounts of urine, or release larger amounts of urine suddenly.

For women, urinary incontinence may happen regardless of age, but it’s most likely to occur in older women. Almost half of women 65 and older have some type of urinary incontinence.

Signals that you have an incontinence issue that merits seeing a urologist include spasms or pressure in the pelvic area, causing an urgent need to urinate. Also frequent trips to the bathroom, for example, more than eight times per day or more than two per night while you sleep.

Your doctor will give you a plan of treatment, starting with steps that you can do at home. If these activities don’t improve symptoms, your doctor might recommend seeing a urologist or recommend other treatments, depending on whether you have urge incontinence or stress incontinence, or both.

What You Can Try at Home

Your doctor, nurse or urologist may suggest exercises that you can do at home. These preventative activities may stop urinary incontinence, or help you leak less.

Here are some of the activities that may be prescribed:

  • Kegel exercises. Kegel exercises targeted to strengthen the pelvic floor can help. However, some women’s pelvic floor muscles remain tightened all the time. In those cases, Kegel exercises not only will not help your urinary symptoms but they may cause more problems.
  • Bladder training. Going to the bathroom at regular times can help control an overactive bladder and help urge incontinence. You will be asked to keep a bladder diary to track how often you make a trip to the bathroom. You then will add 15 minutes to the intervals between bathroom visits. You should urinate each time, regardless of whether or not you feel an urge to go. You will be incrementally increasing the time between visits. Eventually your can train your bladder to retain more urine before it needs to be emptied.
  • Losing weight. Having extra pounds adds pressure to the bladder and surrounding muscles, which can cause bladder control problems.
  • Changing eating habits. Drinks with carbonation, alcohol or caffeine may aggravate incontinence.
  • Treating Constipation. Try eating more fiber because constipation can worsen urinary incontinence.

Urinary incontinence does not need to be a normal part of aging. It is sometimes a signal of another health problem, such as weak pelvic floor muscles. There are different types of treatment available to help ease the problem. Our team of specialists at Advanced Urology Institute have years of experience working with patients with urinary incontinence and can develop the best plan for the individual’s needs. For more information, visit the Advanced Urology Institute website.

What Causes a Urinary Tract Infection?

Urinary tract infections, or UTIs, can be diagnosed based on either symptoms or a urine sample test. The good news is that most urinary tract infections can be cleared up in 2 or 3 days of treatment. When the bacteria of the genitourinary tract are out of balance, there is more opportunity for micro organisms like E. coli to thrive. Here are some causes of UTIs:

  • Difficulty with being able to empty the bladder completely
  • Bowel incontinence
  • Kidney stones
  • Diabetes
  • Poor personal hygiene
  • Some types of birth control, including spermicides
  • Use of tampons
  • Frequent and/or intense sexual intercourse, especially with new partners
  • Pregnancy or menopause
  • Having a catheter
  • Long-term immobility
  • Suppressed immune system
  • Prolonged use of antibiotics

If you believe you have a urinary tract infection, you should see a doctor as soon as possible for treatment. While most UTIs aren’t serious, they can be very painful and they can also develop into more serious problems such as kidney infections.

Symptoms that might indicate a UTI include:

  • frequent or strong urges to urinate
  • cloudy, smelly or bloody urine
  • burning pain when urinating
  • nausea and vomiting
  • muscle aches in the lower back and abdominal pains

Prevention is preferable to treatment, and these practices can reduce your risk of developing a UTI:

  • Drink plentiful amounts of water and urinate frequently.
  • Avoid alcohol and caffeine, as they can irritate your bladder.
  • Urinate before and shortly after sex.
  • After using the toilet, remember to always wipe front to back.
  • Shower instead of taking baths.
  • Consume cranberries. While cranberry extracts don’t actually treat UTIs, they are effective in reducing your risk of recurrent UTIs. Try cranberry extract tablets, which can be twice as effective as drinking cranberry juice.
  • Regularly taking probiotics, especially after completing a course of antibiotics, may lower your risk of UTIs.
  • Be vigilant about keeping the genital area clean.
  • Choose cotton underwear and loose-fitting clothing.

Diagnosis and Treatment

Consult with your doctor if you develop symptoms of a urinary tract infection. Diagnosis includes assessing symptoms and following up with testing a sample of urine to analyze counts of bacteria, white blood cells and red blood cells. Since UTIs happen due to an imbalance of bacteria, the most common treatment is antibiotics or antimicrobials.

Prescription or over-the-counter pain relief meds can alleviate pain. You also can try putting a heating pad on the abdomen or back.

If you think you have a UTI, you may wish to contact St Pete Urology for a consultation. For more information, visit the St Pete Urology website or make an appointment with one of our board-certified physicians.

BPH: What Is It and What Causes It?

BPH: What is it and What Causes it?BPH is the abbreviation for benign prostatic hyperplasia, also called prostate gland enlargement, a condition commonly found in men as they age. Enlarged prostate glands can cause serious urinary issues such as blocked urine flow, urinary tract issues and kidney problems. The treatments for BPH include medications and minimally invasive surgery.The most common symptom is an urgent and frequent need to urinate. These may be accompanied by a difficulty beginning urination, a weak and interrupting stream, extended dribbles at the end of urination, or an inability to completely empty the bladder during urination. Urinary tract infections and bloody urine are other less common symptoms.

It is important to note that the size of the prostate does not necessarily correlate to the enlargement of the prostate. For instance, some men may have prostates that are only slightly enlarged and still suffer from symptoms worse than men with far greater enlarged prostates.

The prostate gland is found just below the bladder, and the tube that allows urine to exit the body runs directly through it. This is why urine flow is affected when the prostate enlarges. The primary cause of BPH is not fully known, but it may be related to changing sex hormone levels in men as they age.

The main risk factor for BPH is aging. Although BPH rarely affects men under 40, one-third of men between the ages of 40 and 60 experience it. And half of men experience it by age 80. Family history also plays a role in your chances of developing these problems. Men with a blood relative with BPH are more likely to develop it themselves. Diabetes, heart disease and obesity all increase the risk factors as well, while exercise helps lower them.

There are several complications that can result from BPH. The most common one is the inability to urinate, which may require a catheter if severe enough. Urinary tract infections can occur as well. Bladder stones and bladder damage may occur when the bladder cannot be fully emptied, which is more likely to happen to someone with BPH. Kidney damage is another complication that occurs when pressure that has built up in the bladder directly damages the kidneys.

Although common, BPH is a serious condition that can negatively affect quality of life and well being. But with many treatment options available, men can find relief by promptly seeking medical help. The doctors at St Pete Urology specialize in treating these issues and improving the lives of men as they age.

How soon can I have sex after a vasectomy?

Men have a vasectomy in order to not have to worry about conception when they are making love. A vasectomy is one of the few ways men can have control over their reproductive capacity. It’s also one of the most reliable ways to prevent an unwanted pregnancy.You may have questions before or right after having a vasectomy. Here are some answers to the most frequent questions.

What is a Vasectomy?

Considered a minor surgery, a vasectomy is when the vas deferens is cut and the two ends are seal and tied together. Depending on factors that your urologist can discuss with you, you will either have a conventional vasectomy or a “no-scalpel” vasectomy.

During a conventional vasectomy, the surgeon will make one or two small incisions in the skin of the scrotum to access the vas deferens. The surgeon may remove a small piece of the vas deferens before searing the ends and tying them off with a suture. The procedure is repeated on both sides. The small cuts in the scrotum may be closed with dissolvable stitches or simply left to close on their own.

For a no-scalpel vasectomy, your urologist will locate the vas deferens by feeling for it under the skin of your scrotum and place a small clamp on the vas. A minute hole is made in the skin, which is stretched open so the vas deferens can be lifted out to cut, and then the ends are tied or seared, and replaced.

What will sex be like?

A vasectomy is a fairly simple procedure without long-term effects on sexual activity. Your surgeon may recommend abstaining from sex for a short time afterward. This is to allow the incisions and sutures time to heal.

Normally the recommendation is to wait for any pain or swelling to resolve before having sex. The reason you should wait to have sex is because if it is too soon, you could reopen the site of the incisions and infection-causing bacteria might enter the incision.

Most men can resume sexual activity within a week or two. During the time shortly after your vasectomy you should use an alternative form of birth control because it takes a little while before all the sperm is cleared from your ejaculate. Your doctor will test your semen sometime after surgery, usually around six to twelve weeks.

Having a vasectomy rarely changes anything about ejaculation or orgasm. There are a few cases of post-vasectomy pain syndrome. But most patients have only the following post-surgical inconveniences which generally go away on their own:

  • mild to moderate pain or discomfort
  • bruising or soreness of the scrotum
  • blood clots in the scrotum
  • swelling in your genital area or scrotum
  • blood in the semen

Having the peace of mind that a vasectomy delivers sometimes can enhance sex life, with better arousal and erections. About three months after your surgery, you can have unprotected sex without fear a possible pregnancy. However, it is always wise to use protection with a new partner.

Facts About Stress Urinary Incontinence in Women

What Is Urinary Incontinence?

Many women have a silent concern due to urinary incontinence. It somehow seems taboo to talk about the problem, even with a regular doctor or gynecologist. There are approximately 25 million Americans who suffer from some type of urinary incontinence and as many as 80 percent of them are women. Pregnancy, giving birth, going through menopause and even the unique structure of the female urinary anatomy contribute to the disparity between male and female sufferers.

Urinary incontinence is defined as the unintentional loss or leakage of urine. The term “stress incontinence” means that when the body is under exertion it puts pressure on your bladder and the bladder leaks. Some triggers for stress incontinence include running, coughing, sneezing, bending or heavy lifting.

Bladder Retraining

The bladder is controlled by muscles and it can be trained. You may wish to keep a voiding diary, noting things like times of urination, duration between bathroom trips, types of food or beverages that seem to trigger urgency or frequency of bathroom trips. This journal describing your symptoms and potential causes can help if you need to visit a urologist for treatment.

As you establish baselines for your urinary problem, you can start behavior modification and training your bladder. Here’s how to do it:

  • Schedule Your Bathroom Breaks

Start by scheduling bathroom visits. Increase the time periods between those breaks by adding 15-minute increments. Visit the bathroom even if you don’t feel you need to go. You will be working toward longer and longer stretches of time between breaks.

  • Perform Kegel Exercises

When you learn to isolate the muscles that control urine flow, you can practice having more control by performing Kegel exercises while sitting, standing or during urination.

Other Tips to Prevent Overactive Bladder:

  • In addition to bladder retraining, you may want to eliminate or limit beverages that increase the need for urinating, like coffee, tea or caffeinated sodas.
  • Drink fewer fluids before bedtime.

Treating Overactive Bladder With Behavioral Modifications

You needn’t feel alone when you have urinary incontinence. Make an appointment with a urologist who is trained to deal with your condition. Your doctor may take any of the following approaches beyond what you can do on your own:

  • Recommend biofeedback,
  • Send urine or drawn blood to the lab to determine how completely you empty your bladder.
  • Prescribe medicine to address bladder function or tighten muscles.
  • Employ a medical device, such as a urethral insert or a pessary.
  • Try nerve stimulation, using a mild electric current to nerves in the bladder that help control urination.
  • Suggest surgery if indicated.

If you have stress incontinence, you may be limiting yourself from fully participating in life events. Seek treatment from experts like those at St Pete Urology, where surgeons perform hundreds of successful sling surgery procedures every year. For more information, visit the St Pete Urology website.

How to tell if your prostate is enlarged?

The prostate gland is an integral part of the male reproductive system. It secretes seminal fluid, which nourishes sperm as they grow and facilitates their transportation during ejaculation. It is located between the bladder and the rectum and surrounds the base of the urethra. Due to its location next to key parts of the urinary system, the health of the prostate gland tends to have a direct impact on the health of a man’s urinary system.

The prostate gland grows larger as a man ages. While this gradual enlargement is normal, by the time a majority of men turn 50, the prostate has reached a size where it may start to affect the normal functioning of the urinary organs near it. It is at this point that a man is said to have an enlarged prostate, or clinically speaking, benign prostate hyperplasia (BPH).

Signs and Symptoms of an Enlarged Prostate

An enlarged prostate presses, pinches or causes a blockage in the urethra. The urethra carries urine from the bladder to outside the body. The direct effects of an enlarged prostate are manifested by difficulty in the discharge of urine. These difficulties could be in the form of:

1. Frequent and sudden urges to discharge urine;

2. Difficulty starting a urine stream;

3. Weak urine stream; and

4. Dribbling urine.

If left untreated, the effects of an enlarged prostate can cause the following complications:

1. Acute Urine retention. This is a complete inability to pass urine. Medical attention must be sought immediately if this occurs;

2. Urinary tract infections;

3. Blood in the urine;

4. Pain when passing urine; and

5. Pain in the lower abdomen.

Sometimes an enlarged prostate does not produce symptoms. When this occurs in some men, it may not even be possible to diagnose the condition because it gives them no trouble at all.

The key to diagnosing and treating an enlarged prostate lies with frequent prostate monitoring by a qualified urologist. Men approaching age 50 should get tested or at least keep a watch out for any of the symptoms listed above. The good news is there are many successful treatment options for the condition. Our specialists at St Pete Urology are experienced and well qualified to help with any questions, concerns and treatment. If you think you may have an enlarged prostate, or are experiencing any problems, by all means contact us. For more information, visit the St Pete Urology website.

Can a vasectomy fail?

A vasectomy is a form of male contraception that is administered through a minor surgical procedure. During a vasectomy, the patient’s vas deferens are cut and the ends are tied up or seared so they are blocked. The vas deferens is made up of two narrow tubes that transport sperm to the ejaculatory duct during ejaculation. A vasectomy inhibits the transportation of the sperm to the duct, so only seminal fluid is discharged when a man ejaculates. The absence of sperm removes the possibility of conception. A vasectomy is considered to be the most efficient form of birth control. However, there are instances, though very rare, in which pregnancy occurs even after the man has had a vasectomy.

Reasons why a vasectomy may fail

1. Recanalization

This is a medical term for when the cut vas deferens reconnect and revert to something like what they were before the vasectomy. This process happens naturally when tissue from the cut ends gradually grows until the two ends reach one another and reconnect.

Tiny channels also can form in the healing scar tissue of the snipped vas deferens and provide a passageway for sperm from one end of the vas deferens to the other.

2. Surgical error

In very rare cases, surgeons have been known to make an error during the procedure. This might mean either that the vasectomy was not done at all or that it was done in a manner that might cause it to fail.

Such errors could be:

a. Cutting one vas deferens and leaving the other;

b. The surgeon cuts completely different tubes that are not the vas deferens; and

c. In the very rare cases where the patient has duplicated vas deferens, that is to say two vas deferens on each side rather than one on each side as is the normal case, and the urologist cuts only one of the two .

d. Having intercourse too soon

Men who have had vasectomies are always advised to avoid having sex too soon, and if they do, to use another form of contraception. This is because semen does not become clear of sperm immediately after the vasectomy. The standard practice is to wait for three months after the procedure. After the three months, a urologist should conduct a semen analysis and advise accordingly.

Vasectomies are largely successful. Any man considering it has absolutely no reason to fear that it will fail because they rarely do. However, after undergoing the procedure, the patient must take care to observe all guidelines given by the urologist. A little anxiety before the procedure might be expected but the advice of a trained urologist, such as those available at St Pete Urology should dispel the worry. The team of specialists at St. Pete Urology can help with questions, consultation, surgery and follow up steps for a vasectomy. For more information, visit the St Pete Urology website.
